array-unique
Advanced tools
The array-unique npm package is a small utility that removes duplicate values from an array. It is useful when you need to ensure that an array contains only unique items without having to write custom deduplication logic.
Deduplicate an array
This feature allows you to remove duplicate values from an array, resulting in an array of only unique items. The `arrayUnique` function is used as a callback for the `filter` method.
[1, 2, 2, 3, 4, 4, 5, 5].filter(arrayUnique)Lodash is a popular utility library that includes a `uniq` function. This function is similar to array-unique in that it removes duplicate values from an array. Lodash offers a wide range of additional utility functions, which makes it a more comprehensive solution than array-unique, but also larger in size.
Underscore.js is another utility library that provides a `uniq` function, similar to array-unique. It is comparable to Lodash in functionality and size, and it also offers a wide range of utility functions beyond array deduplication.
Ramda is a functional programming library that includes a `uniq` function. It is designed with a focus on functional programming patterns and immutability. Ramda's `uniq` function provides similar functionality to array-unique, but within the context of a larger functional programming toolkit.
